Sand Storm
From AmtWiki
A type of Terrain from 1001 Amtgardian Nights.
Description
This is an all encompassing terrain effect. It is not in any one area, but the entire battle field. All players have limited visibility (see Darkness) and their movement is slowed to a walk. If a character tries to run or move quickly, they will take a wound to a limb (reeve’s choice).
